Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Send a Permissions-Policy header — Camera, microphone and geolocation stay switched off for embedded content.
- Make the language selector focusable — Keyboard users can change the language.
- Show a visible focus indicator — Keyboard users can see where they are on the page.
- Make every id on the page unique — Anchors, labels and scripts reach the element they were pointing at.
- Shorten the over-long titles — The whole title stays visible in search results.
- Publish JSON-LD structured data — Rich results (ratings, breadcrumbs, business details) become possible.
What the site checks found
- Low — SEO — No entry in the sitemap carries a lastmod date, so crawlers cannot tell which pages have changed since they last read them.
- Low — SEO — Pages the crawl found that the sitemap does not list: 1 of 5 — crawlers have to reach them through links alone.
- Low — Security — The Content-Security-Policy sets no object-src, so those are left at the browser default.
- Low — Security — The Content-Security-Policy allows 'unsafe-inline' for styles — script injection is still blocked, but injected CSS can repaint the page and leak what is on it.
- Low — Security — The zone is not signed with DNSSEC, so a forged DNS answer cannot be detected.
- Low — Performance — The HTML is compressed with gzip but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
- Medium — Links — Internal links leading to an error page: 1 of 10 checked.
